That's not true. There is nothing preventing a classic NIC driver from implementing some/all switchdev ops if the device can do forwarding offload or other switchy-things. This patchset is about a switch feature (MLAG was the example use-case), so let's move this under switchdev. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
